Problems and solutions of cathode - ray phosphors for projection tubes
投影管用荧光粉的问题及进展
Auto - e - focus system means that voltage of focus polar can be auto adjusted . and auto - optics - focus system means that the optic system composed of screen of projection tube microscope and area ccd can be auto focus
自动电聚焦指对投影管聚焦极电压的自动调整，而自动光学聚焦系统是指对投影管发光屏?显微镜? ccd组成的光学系统的自动聚焦。
In this dissertation a new system that test crt projection tube resolution is bring forward against deficiency example slow test speed great affection because of artificial factor in the line - resolution - test system
本文针对crt投影管分辨率线阵ccd测试系统测试速度慢、人为因素影响大、只能测试一维方向分辨率的缺点，提出了一种新的分辨率测试系统。
The system could rest projection tube resolution in two dimension adopting area - ccd , but also raise precision and speed of resolution - test because of realization of auto focus system that absolutely exclude the affection because of artificial factor . auto - focus system include auto - e - focus system and auto - optics - focus system
该系统不仅采用面阵ccd使该系统能够测试投影管二维分辨率，而且由于实现了自动聚焦系统使得分辨率测试完全不受人为因素的影响，大大提高了分辨率测试的精度和速度。
